Before connecting the appliance to the gas supply line, double check that the appliance you
have purchased is designed for the gas type you are using. The gas type markings are
located on the certification label and also on the appliance’s gas valve.
Adequate clearance for proper installation and checking of the gas connections must be
provided. All gas connections must be checked for gas leaks.
Have your gas supplier or a qualified gas fitter run a gas supply line into the gas fireplace.
The line must be properly sized and fitted according to the installation codes. Upstream of
the supply connection, the fitter shall provide a manual shut-off valve.
CAUTION:
The appliance and its individual shutoff valve must be disconnected from
the gas supply piping system during any pressure-testing of that system at test pressures
in excess of ½ psig (3.5 kPa). The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during any pressure-testing of the
gas supply piping system at test pressures equal to or less than ½ psig (3.5 kPa). Failure
to do so will damage the appliance’s gas valve. Such damage is not covered by the
manufacturer’s warranty.
INSTALLATION INSTRUCTIONS
1. Open the lower grills.
2. The pressure test taps are located on the valve. The taps are located in the gas valve
front face. The inlet is marked ‘
IN
’ and the outlet is marked ‘
OUT
’. (See Fig.1)
3. Loosen the set screw inside the tap with a ⅛ ” (3 mm) wide flat screw driver.
4. Connect a ¼” (6 mm) rubber tube to the tap post and a manometer.
5. Verify the readings obtained are within specs (as shown on the appliance rating plate)
6. Be sure to tighten the set screw inside the tap after you are finish taking pressure
readings.
7. Check for leaks.

The minimum permissible gas supply pressure is 4.5 in. w.c. (1.12 kPa) for natural gas and
11.0 in. w.c. (2.74 kPa) for propane. Maximum gas supply pressure should never exceed
14.0 in. w.c. (3.48 kPa) or ½ psi. for both natural gas and propane.
BE SURE TO
TIGHTEN THE PRESSURE TAP SET SCREW AFTER CHECKING THE PRESSURE.
